Get ready to shop the new Viva Glam Rihanna collection from MAC, out in September.

The frosted metallic mauve lipstick will retail for $16, while the lip gloss will sell for $15, when the duo launches in September at all MAC locations. Fans of the first Viva Glam's rich reds needn't fret as RiRi's original collection is still available, too.

The icing on top of the frosted shades? "Every cent of the selling price of Viva Glam Rihanna goes toward helping women, men and children living with and affected by HIV/AIDS," according to the press release.
